To all whom it may concern:

Be it known that I, OSCAR L. SCALBOM, a citizen of the United States, residing at Chicago, in the county .of Cook and -State of Illinois, have invented certain new and useful Improvements in Signals, of which thefollowingis a specification.

This invention relates to improvements in signals, particularly adapted though not necessarily limited in its use with flash operate with the light to produce thedesired signal, and which" mayas readily be de tached therefrom. V

To the attainment of these ends and the accomplishment of other new and useful ob jects as will appear, the-invention consists in the features of novelty in substantially the construction, combination andarrangement of the several parts, hereinafter more fully described and claimed and shown in the accompany' g drawing illustrating this invention and in which:

Figure 1 is a side elevation of a flash light having an atmchment applied thereto constructed in accordance with the principles.

of this invention. v Fig. 2 is a right hand end elevation of the parts shownin Fig. 1. c

Fig. 3 is a sectional view as taken on line v Fig. 4 is a bottom plan view of the parts shown in Fig. 3.

Referring more particularly flash light provided with a lens casing 11 at one end thereof, and in'which casing thelens is arranged.

The signal attachment which is adapted to be removably applied to the flashlight, com,

of a size slightly larger than the lens casing' 11 and is provided with spring fingers or projections 13, adapted to engage over the r v I Specification bf Letters Patent.

edge of the lens and casing to hold the samesecured to the lens. y r

The body 12 is provided with a series of openings 1410f any desired size and configuration and arranged in any suitable manner with respect to eachother but are in'a posis tion. with respectto the lens so that when"- the openings 14: are uncovered, the. light will be exposed therethrough. The remaining. portion of the body 12 is preferably of a construction as to prevent the light from be; .ing visible except through the openings 14;

when the latter are-uncovered. A. disk 15 is rotatably connected with the body 12' in any suitable manner such as by means of a pivot 16, and a portion of the periphery of "the disk is preferablycut away as at. 17 to any desired extent aroundthe periphery, so that anyone or more of the .openingsyl. may be uncovered by thecutaway'portio'n of, I the disk when the latter iscproperly posi- 7.5 tioned with respect thereto.

The disk is provided with an operating handle 18 adapted to project through a suite ableslot 19 in the body 12; sq thatby-the.

movement of the handle. 18, the cutaway portion 17 of the peripheryof the idisk may be movedso, as to uncover anyone "or more "er. the openings 14. r

In order to, assist theoperator in posi-- tioning the disk 15 with respect to the openings 14, and to hold the disk when thusadjusted, any suitable temporary locking means may-be provided, such for instance as a projection on one of the parts and spaced recesses on the other parts to receive the projection.

In the present form of-the a projection 20. is shown on the disk'15 and spaced recesses 21 are shown-on the body 12 adapted to receive the projection. The natural sprin of the parts with respectfto each other will suflicient to permitthe parts to yield so that the projection 20 may be moved out of one recess 21 and into the next recess,

This invention is particularly ad'vantageous for use in theaters or halls or other places, where it is desired to seat people,,as the usher at one end of the aisle can signal to another personcatanothernpoint in. the house and seats, without necessitating a trip of the usher to the entrance each time vacantseats are found at diflerent points in the house.

-' 1.'In combination, a flash light embody-.

ing a light opening, a signal device arranged to extend across said opening, and spring fingers connected with the signal and adapted to removably and frictionally secure the signal in position, said signal 'device embodying means whereby the signal may be varied at will.

2. In combination, a flash light embodying a light opening, a signal device of a size slightly larger than the said opening, and yielding clamping means removably securing the signal in position, saidslgnal device embodying means whereby the signal may be changed at will.

3. As an article of manufacture, a signal attachment for flash lights and the like, said signal embodying cooperating and relatively movable elements adapted to be arranged within the field of light, means for imparting such relative movement to the elements for causing diflerent signals to be given by the light, and means connected with the signal and adapted to clamp the frame of the light opening of the flash light vfor securing the said attachment in position for free removal.

4. A signal attachment for flash lights embodying cooperating and relatively movable elements arranged within the field of light, one of said elements having a series of openings, and means for imparting such relative movement to the elements for causing the other of the said elements to successively close the said openings at will.

5. A signal attachment for flash lights and the like, embodying cooperating and relatively movable elements arranged within the field of light, one of said elements embodying a plurality of openings, means for imparting such relative movement to the elements for causing the said openings to be successively closed or opened, and means for removably attaching said signal in front of the light.

6. A signal attachment for flash lights and the like, embodying cooperating and relatively movable elements arranged within the field of light, means for imparting such relative movement to the elements for causcent the lens,

naeaiea ing difi'erent signals to be given by the light, and means embodying sprmg fingers adapted to removably engage the frame of the light opening for securing the signal in position.

7. In combination, a flash light embodying a lens, a signal device arranged adjacent the lens,'and means for detachably securing the signal device to the frame of the lens, the said signal devige embodying a body having one or more openings therein and through which the light rays pass, and a shutter adjustably connected with the body and adapted to be moved to open or close one or more of the said openings.

8. In combination, a flash light embodying a lens, a signal device arranged adjaand means for detachably securing the signal device to the frame of the lens, the said signal device embodying a body having one or more openings therein and through which the light rays pass, and a shutter movably connected with the body and adapted to be moved to open or close one or more of the said openings, and interengaging means between the shutter and body for releasably securing the shutter in. its adjusted position with respect to the body.

9. In combination, a flash light embodying a lens, a signal device arranged adjacent the lens, and means for detachably securing the signal device in front of the lens, the said signal device embodying a body having one or more-openings therein and through which the light rays pass, and a shutter movably connected with the body and adapted to be moved to open or close one or more of the said openings, said body having a spring portion extending over the periphery of the lens for detachably securing the signal in position.
